Summary

Containerlessly undercooled Ge73.7Ni26.3 alloy melts were successfully induced to solidify at a certain undercooling of 166 or 136 K when triggered by Ni or Si clusters which were produced by ion-beam sputtering. The melts were also induced to solidify during the continuous cooling processes by continuously introducing clusters onto to the sample surface. In this case triggering was made after the melts were cooled to 1073 K, and nucleation happened at 975 and 1009 K when the samples were induced by Ni and Si clusters respectively, much higher than that without triggering which was 904 K.
